Is the car worth fixing when antifreeze goes in the oil?

If antifreeze is mixing with the oil, it typically indicates a serious issue, such as a blown head gasket or a cracked engine block. Repairing this can be costly and may exceed the car’s value, depending on its age and condition. It's essential to assess the overall state of the vehicle and obtain repair estimates before deciding if it's worth fixing. If repairs are prohibitively expensive, it might be more practical to consider replacing the car.
